To all whom it may concern:

Be it known that I, Gimmes EDGAR JEWELL, a citizen of the United States, residing at Auburn, in the county of Cayuga and State of New York, have invented a Temperature-Regulator Motor, of which the following is a specification.

My invention relates to damper regulators and consists in certain novel features hereinafter described reference bein had to the accompanyin drawings which illustrate one form in whic l have contemplated embodyin the invention, and the said invention is fuly disclosed in the following description and claims. Devices of this character usually comprise an apparatus termed the motor actuated loy a weight or 5 ring which requires rewinding at interva s, and which is provided with rotating devices operatively connected with the dampers of a heater, and

with mechanism for arresting the said rotating devices in two different UOSllZlOIlS, and a second apparatus (usually a thermostatic device) located in the chamber or room thetcmperature of which is to be regulated, which is suitably connected with the controlling mechanism of the motor so as to permit or cause an operation of the dampers in accordance with variations of the temperature of' the chamber or room to be heated,

for the purpose of maintaining an even andv regulated temperature therein. determined by the thermostatic device. Such devices are well known in the art and it iscustomary to so connect the rotating devices of the motor to the draft damper of the heater that one half revolution thereof will move the damper into open position and the other half revolution will move it into closed position, In the operation of such devices, it sometimes happens that the caretaker whose duty it is to rewind or otherwise reinstate the motive power of the motor, will neglect this duty, and the last operation of themotor at the close of its operative period effects the opening of the draft damper. This leavc'sithe heater in a dangerous condition, and may result in. the burning out, of the furnace, or a serious accident to the building and occupants.

The object of my present invention i. to..- insure that the last etiective o oration of the motor before theqilo'se 0 its operative period, shall leave the draft damper in closed or safe position, so that no injury shall resuit from "the carelessness ofthe'caretaker,

state the motive power of lhe motor. In Order to accomplish this result Iprovide mechanism operable by the power supply near the close of its operative period for stopping the further operation of the motor in a predetermined position, to wit, with the draft damper in closed position, and this isefi'ected in the embodiment of my invention herein shown and described by disconuccting the thermostatic controlling device from the motor at a time when the damper actuating device thereof is in the predetermined position.

In the accom aanying drawings, which illustrate the embodiment of my invention before referred to, Figure l represents a front elevation of the motor shown supported on a shelf, the front of its frame-work being removed for a clearer view f the intcrior parts. Fig. 2, is an end elevation of the motor showing it connected with the dampers or doors of a heater. Fig. 3, is a View showing a lever arranged in the motor, breaking the electric circuit between the said motor and the thermostat; it also shows the toothed hub by which it is operated. Fig. 4:, is an end view similar to Fig. 2, but having such parts of the motor as obstruct a view of my improvement and not intimately connected therewith, removed. Fig. 5, is a front elevation with all the parts of the motor not intimately connected with the improvement removed, that a clear conception can be had should he fail to rewind or otherwise rcinof its operation. Fig. 6, is a view of a crankweighted part of a chain carrying :1 driving weight, which said plug being pulled by said chain into a confined spat-c against. the

end of a pivotcd lever, causes the latter to yield and force lts oppositecud tlglllbt a hub having a projection or tooth, pushing said hub along the rotating member of the motor into vertical alinement with another pivoted lever which is operated to break the electric circuit withn thermostat during a pre-determined one half revolution of the rotating member, at the end of which said one-halt revn'izition, the crank-arms provided on the rotating member and connected with the dampers or doors of the heater also rest.

Referring to Fig. 1:-a detailed description of one example of construction will be given. The frame-work 1, supports a main driving, rotating member or shaft 2, which carries a main drivinggear 3, connected with a train of wheels. which 'it is unnecessary to describe. A clutched wheel 4, on which is carried a chain 5, a detented disk 6, a hub 7, having a spline-seat T, and a tooth 8, a spiral spring 9, and another hub having'a projection, and the crank-arms 12, are all carried on said main rotating member 2. -The detented disk 6, and the last mentioned hub having a. projection having no intimate connection with the improvement, will not again be referred to. Where the hub '7, passes on the mainrotating member 2, the latter is provided with a spline which passes in, a spline-seat 7 of the hub 7. A shelf 13, is furnished which supports the motor "in desired working position. I, It also supports a box 14, in which is carried a stora e cell or cells 15, or a-battery which is suita ly wiredto a thermostat A.

At a convenient point as seen at 16,- Figs. 1, 2, at, and 5,-is )ivoted a lever 17, the up er endv of which is forked on either side of the rotating member 2, so it may be brought to bear against one side of the hub 7. The opposite or bottom end of said pivoted lever 17,- is broadly flattened and upwardly bent as seen at 17, in Fig. 5,-and is carried in agirtlrpiece 18, the ends. of which are properly secured on the shelf 13. Another pivoted lever l$),-see Figs. 2, 3, 4, and 5,-is pivoted between suitable supports 20, on the shelf 13, being extended upward toward the rotating member 2, and downward through said shelf 13, 'as seen. It is, arranged, beneath said shelf, to have contact with the col'niei-tions to the thermostat as shown at B.

A drive-chain 5, passes on the clutched wheel 4 and is provided with a weight :22, the said clutched wheel being of sprocket form if desired, and so clutched or arranged as tocause the rotating memberto turn toward the weighted end of the chain while 'it is free to turn on said rotating member in the opposite direction. a well known arrangement unnecessary. to describe. The

other end of said chain 5, passes through parts.

The remaining featuresof the motor the girth-piece 18,-and is provided with a plug or stop-piccc23, which is tapered at its end of attachment with the said chain, and continued in any desired length or form; it is plainly seen in Figs. 1, l, and .5.

Crank-arms 152., are provided with a setscrew 24, which fasten them on the rotating member 2, in the position desired. They also are provided with a slot 25, in which a crank-pin 2G, is adjustable, which arrangement provides for the taking up of any unnecessary slack or for lengthening the connections between them and the dampers or doors of the heater.

Referring to the drawings it will be seen that suitable openings are provided in" the shelf 13, at suitable points for-the passage of the chain and the pivoted levers referred to, they being sufficiently extended to permit of the unobstructed movements ot the said which are shown it isthought unnecessary to describe in detail as they are well known to those skilled in the'art, and have been drawn in order that the mechanism to which the improvement is ap lied might be complete and coherent, an also to show there is no ractical interference between the two.

Re erring to Figs. and 5, a clear idea of the operation of the improvement can be had. The several parts described being arranged with due relation to each other as seen, and the crank-arms arranged on the rotary member so as to operate through their connections with the dam rs or doors of the heater in a predetermined manner,

that is: so they may be left closed or otherwise when the motor is brought to a stop, the latter may be left with no further-care or attention on the part of the operator.

hen the'weight on the chain is nearly run down l and its power for actuating the motor nearly exhausted, the tapered end of the plug on; the opposite end of the chain will have been drawn into the confines of the girth-piece 18; The said girth-piece offers .a space wide enough for the tapered end of the plug, to enter unobstructed; but, as. the latter is drawn up into it, the. larger untapercd part comes in contact withv the end and sides of said girth-piece and, giving way to such influence, it is forciblybrought against the flattened end'of the pivoted lever projected therein. This actioncauses the said pivoted lever17,to yield and, swingtoo mg on its pivotal point, its opposite or to 1 most and is forced against the side of t e hub 7, nextto it which latter yielding', is pushed along on the rotating member against the spiral spring 9, until the tooth 8, of the [said hub 7,is' brought into alinementwith the top end of the pivoted lever 19. As soon 'as the said tooth has. through the turning of the rotating member. been. brought to bear against the top of said pivoted lever 19, the

latter yields and the electric circuit. with the thermostat A. is broken; It should be observcd that the breaking of the circuit as above described does not of itself stop the motor, which will operate until it completes the half revolution through which it is then moving, the damper actuating parts being to secure by-lieitcrs Patent of the United till cornea brought to rest by the. stop lever forming part otthe usual stop mechanism, which I have shown but have not thought-it necessary to describe. .In the device shown inthe drawings the motor will be arrested by said stop lever immediately after the operation of the switch lever 19, and the damper actuating mechanism will be in the draft closed position. When the plug 23, on the chain is withdrawn from the girth piece,- which is done in the operation of Winding up -,-the pressure on the lower end of the pivoted lever '11, is relaxed and the spiral spring 9, on the rotary member retracts against. the hub 7, and crowds it against the forked. top end of the pivoted lever 17, which now assumes its normal position as shown in positive lines in Fig. l'ifiuring this action the tooth of the hub 7, has been released from the end of the pivoted lever 19, which through the retraction of a spiral. spring 21, provided for the purpose, causes it to resume its first position as shown in Fig. 1,'thus establishing the electric circuit when the motor again becomes operative.

it) will be evident to those skilled in the art that other and various forms of construe lion can be had and the spirit of my invcntion remain the same.
